Irreversible Jaynes Engine for More Efficient Heating
-
and
Abstract
Thermal heat efficiency, represented by the heating gain factor, is calculated by using non-equilibrium thermodynamics of discrete systems, thus replacing former estimations and results by finite-time thermodynamics. For performing this calculation, an irreversible Jaynes engine is introduced and compared with conventional heating by heat conduction. Starting out with the second law, represented by Clausius inequalities for the particular parts of the Jaynes engine, the heating gain factor is expressed by their efficiency factors. The entropy productions of the reversible and the totally irreversible limits are considered. The profit of heat supply and the higher stationary temperature of the heated room obtained by using a Jaynes engine are calculated. Comparison with the conventional heating demonstrates that fuel saving is possible by changing the traditional heating technology.
